react-native-search-api

React Native Search Api module

The SearchApi module gives you a general React Native interface to interact with the iOS Search API, Core Spotlight.

For more information about iOS Search APIs, see https://developer.apple.com/ios/search/.

Installation

Automatic part

1. npm install react-native-search-api --save
2. react-native link

Manual part

To the top of your AppDelegate.m add the following line:

#import "RCTSearchApiManager.h"

In your AppDelegate implementation add the following:

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray * _Nullable))restorationHandler {
    return [RCTSearchApiManager application:application continueUserActivity:userActivity restorationHandler:restorationHandler];
}

Usage

Subscribe to the search item open events in your components like this:

componentDidMount() {
    <...>
    SearchApi.addOnSpotlightItemOpenEventListener(this.handleOnSpotlightItemOpenEventListener);
    SearchApi.addOnAppHistoryItemOpenEventListener(this.handleOnAppHistoryItemOpenEventListener);
}

To prevent memory leaks don't forget to unsubscribe:

componentWillUnmount() {
    <...>
    SearchApi.removeOnSpotlightItemOpenEventListener(this.handleOnSpotlightItemOpenEventListener);
    SearchApi.removeOnAppHistoryItemOpenEventListener(this.handleOnAppHistoryItemOpenEventListener)
}

In order to create a new spotlight item, use indexSpotlightItem or indexSpotlightItems:

SearchApi.indexSpotlightItem(item).then(result => {
    console.log('Success');
}).catch(err => {
    console.log('Error: ' + err);
});

To add new items to the app history, use createUserActivity:

SearchApi.indexAppHistoryItem(item).then(result => {
    console.log('Success');
    that.setState({labelText: 'Success'});
}).catch(err => {
    console.log('Error: ' + err);
    that.setState({labelText: ('Error: ' + err)});
});
